Speed limit review

The speed limit review

In August 2006, the Department for Transport published a guidance document called Circular Roads 01/2006 "Setting Local Speed Limits". To achieve the aims of the guidance, the government required all traffic authorities in England to review the speed limits on A and B roads by 2011.

The method for carrying out the review was set by initially reviewing an area, south of Maidstone, with some 76 miles (122km) of A and B roads, called the demonstration area, which was completed in 2008 and the speed limit changes resulting from this implemented at the start of 2010.

The remaining A and B roads were to be reviewed, as part of the speed limit review project. The recent withdrawal of government grants has led to the suspension of the speed limit review. Any further work on the project and implementation is under consideration by Kent County Council. It therefore unlikely that speed limit changes will be progressed on an area wide basis.

However, where crash analysis indicates that a lower limit is wholly or partly the measure required to reduce crashes on a section of road, then this can be treated as a crash remedial measure (CRM) and prioritised and funding bid for accordingly. 

Circular Roads 01/2006 "Setting Local Speed Limits".

The principle intention of this document is to bring about a more consistent approach to the application of speed limits, as clearly indicated by the opening statement of the Circular.

"Speed limits should be evidence-led, self-explaining and seek to reinforce people's assessment of what is a safe speed to travel. Speed limits should encourage self-compliance and not be seen by drivers as being a target speed at which to drive in all circumstances..."

The guidance also seeks to address the balance between the need to travel with the need to improve quality of life.

Setting speed limits using this circular will:

  • assist the motorist in assessing a safe speed at which to travel
  • consider the effects on people who live adjacent to a trafficked road.

However, these effects must be balanced against the need to keep traffic moving throughout Kent to enable business and other day to day activities to function.

Some of the issues considered in the speed limit review project

The speed of traffic is of local concern, but the introduction of some lower speed limits produced the inconsistency the government guidance looks to avoid. In some cases, resulted in the introduction of limits where the overall speed of traffic was not changed, and which did not always have the support of Kent Police.

Recommended speed limit changes as part of the review were considered as a whole, rather than on an individual change, to achieve consistent self-enforcing routes. Speed limits should not be seen as a target. We should all drive within the constraints and limitations of the road and accept that the majority of drivers using these roads are the people who live there.
